Parallel Port

When communicating via the parallel port, the values selected must be the same as those used by the host equipment connected to the printer. Port selection for status information is determined by the channel sending the request. The parallel port can be set for bidirectional or unidirectional communication. The default setting is bidirectional.

A standard 36-pin parallel connector (Figure 30) is available on the back of the printer for connection to the data source.

Table 8 shows the pin configuration and function of a standard computer-to-printer parallel cable.
